To ensure you don’t over-survey your customers, we’ve provided the option of survey throttling. This can be found under Survey Throttle in your account settings, or on the verification page in your campaign settings before you launch.
One Day Throttle
Our system has a built in one day throttle so that any one contact cannot be surveyed more than once in a 24-hour period from your account. This is to help prevent accidental sending and over-surveying your contacts.
Due to this, you may need to use variations of your email(s) while testing.
Ex: firstname.lastname@example.org, email@example.com...
You can choose a setting of 30, 60, 90, or 180 days, and your customers will not be surveyed more than once during that time period. If you choose to have your surveys dripped, throttling will be factored in and surveys will be scheduled accordingly. This is a global setting and applies to all campaigns and all contacts.
